flight 3: blank screen after installation (ATI x700/FireGL V5000)

xorg.conf as created by installation.

Xorg.0.log of reboot after installation.

I have also tried with fglrx drivers (xorg-driver-fglrx) and the result was the same.
I have also in the mean time upgraded dapper (apt-get dist-upgrade) and got latest xorg packages (7.0.0-0ubuntu10).

As this also did not help, I have looked in my Breezy install for proper modes for built-in LCD.

I have added the following lines to Monitor section:
        HorizSync 73.2
        VertRefresh 60

Now everything works (currently using fglrx driver: 6.9.0-8.20.8+2.6.15.4-3

I would say that there is something different in monitor detection in xorg 6.8.2 (Breezy) and xorg 7.0 (Dapper). However, this have worked out-of-the-box in Flight 2, therefore it is some change after Flight 2.

Xorg.0.log now when I got it working (DF3 + dist-upgrade + fglrx + Sync in Monitor section)

Log from Breezy (6.8.2 using 8.21.7 driver from ati.com - Monitor autodetection works)

This seems to be fixed in recent updates, as I could remove HorizSync and VertRefresh and everything still works (with fglrx).

I will retest this after fresh install of Kubuntu Dapper Flight 4 (with default "ati" driver).

I have installed Kubuntu Flight 4 from scratch and this problem is still there. HorizSync/VertRefresh does not help for "ati" driver.

I have then tried "radeon" driver and it works without manually setting sync ranges.

How does Ubuntu install decides which driver is appropriate for which card? It looks like that "radeon" driver in X.org 7.0.0 is much better than "ati"driver (at least on my hardware).

I can confirm the problem with Ubuntu Dapper Flight 4 (Live CD) on my HP nw8240. My solution was to Alt-F1 to a prompt, edit xorg.conf to add a 1920x1200 resolution and things seemed to work just fine after that.

At no point when booting the Live CD does it ask for resolution. xorg.conf defaults to 1024x768 which, for some reason, doesn't work (or shows up as blank).

"ati" driver now works if I add the following in "Device" section of /etc/X11/xorg.conf:

        Option "MonitorLayout" "LVDS,NONE"

In addition, screen size is not properly detected with "ati" driver ("fglrx" works OK) - this causes the display to be configured with 75 DPI instead of 147 DPI.In order to workround, I had to set it manually set display size in "Monitor" section of /etc/X11/xorg.conf:

        DisplaySize 330 210

After recent updates (not sure when, as I was running "fglrx" for some weeks), "ati" driver requires also to specify Sync ranges in Monitor section:
        VertRefresh 70-75
        HorizSync 60

Hi all!

Yesterday I tested a nightly build and I had still a blank screen at first boot.
My system is a amd64 and a Radeon R9250.
With Breezy I have the same problem wenn I use the fglrx driver, but it runs with the xorg driver.
On my Latop (ATI Mobility Radeon X700) there only runs the fglrx driver,
I have a blank screen with the xorg driver.

Can you confirm if this still happens with the latest Flight 6 release?

I cannot test this with Flight 5/6 as install CD does not boot due to bug 34592, but I suspect the bug is still there as the X server still need to have MonitorLayout (to get screen output) and DisplaySize (to properly set DPI).

Please confirm if this still persists with Dapper Beta. Thanks

I installed the beta from CD (on my nw8240) and X booted up blank. I had to install fglrx before seeing anything. This time, however, I didn't have to edit xorg.conf to add the 1920x1200 resolution.

Just tested Ubuntu Beta Install CD and this problem is still there on my HP nw8240 with ATI FireGL V5000 PCIE.
Adding MonitorLayout to xorg.conf (see above - comment from 2006-02-24 22:28:13 CET) fixes it for me.

I can confirm this bug is still present in the live cd for amd64 of Kubuntu Dapper 6.06 LTS on Acer Aspire 5024 with Ati Mobility Radeon X700

I also have this problem with Kubuntu Dapper 6.06 LTS on Acer Aspire 5021 with X700, easiest sollution form me is adding Option "MonitorLayout" "LVDS,AUTO". Breezy with fglrx needs this too.

The MonitorLayout issue on X700 is bug #22985. There are some other issues mixed in here, please file separate bugs for those if needed. The HorizSync problems should be fixed with this release, see the referred bugs for info:

xorg (7.0.0-0ubuntu33) dapper; urgency=low
  * Make sure to always write sync rages with ati driver and lcd/lvds
    monitors. According to bug #39762 this is always required.
    Also cleanup the ati code that was forcing MONITOR_SYNC_RANGE later
    in the process since it is now catched by the more generic one.
